PRELIMINARY  
Intel® 82340FX PCIset Level II  
Cache Module Family  
CYM74B430 is an asynchronous 256-Kbyte cache module that  
provides a low-cost, high-performance solution with industry stan-  
dard 32Kx8 5V SRAMs and 3.3V level translators. The  
CYM74B430 is organized as 32K by 64-bits with an 8Kx8 tag that  
supports 3-2-2-2 read and 4-2-2-2 write cycles at CPU bus speeds  
up to 66 MHz.  
Features  
•
Pin-compatible secondary cache module family that ad-  
heres to the Intel COAST 1.1 specification  
•
Asynchronous (CYM74B430), synchronous pipelined  
(CYM74P430, CYM74P431), or synchronous  
(CYM74S430, CYM74S431) configurations with pres-  
ence and configuration detect pins  
The synchronousmodules are available with low cost synchro-  
nous pipelined RAMs, or high performance synchronous burst  
RAMs. The synchronous pipelined modules are based on a  
16Kx64 RAM. The CYM74P430 is a 256-KB module while the  
CYM74P431 is a 512-KB module.  
•
Ideal for Intel® P54C-based systems with the 82430FX  
(Triton) chipset  
•
•
Operates at 50, 60, and 66 MHz  
The CYM74S430 and CYM74S431 are high performance syn-  
chronous burst cache modules that provide 256 KB and 512 KB of  
cache respectively. The modules support 3-1-1-1 performance at  
66 MHz. Multiple ground pins and on-board decoupling capac-  
itors ensure high performance with maximum noise immunity.  
Uses cost-effective CMOS asynchronous SRAMs or  
high-performance synchronous SRAMs  
•
160-position Burndy DIMM CELP2X80SC3Z48 connec-  
tor•3.3V compatible inputs/data outputs  
All components on the cache modules are surface mounted on  
a multi-layer epoxy laminate (FR-4) substrate. The contact  
pins are plated with 150 micro-inches of nickel covered by 10  
micro-inches of gold flash.  
Functional Description  
This family of secondary cache modules is designed for Intel  
P54C systems with the 82430FX (Triton) chipset.
